Application filed May 20. 1907. Serial No. 374,639.

' hook I). the top face of which forms a right have invented certain new and useful improvements in Bed-Plates for iron Railwayhleepe s; and i do hereby declare the following to be a full. lear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference angle to said latter end, r... shown in Figs. 1 to 4. and lies parallel to the underface of the chair at a distance therefrom equal to twice the thickness of the top of the sleeper.

The lug is of the same thickness as the sleeper top for a distance slightly greater than the length of the lip of the book, so that the combined length of the lip and 5 lower part of the lug is a little less than the being bad to the accompanying drawings,

and to letters or tigures of reference marked thereon, which form apart of this specificatlnll.

My invention relates to rail chairs adapted to be used on hollow metal sleepers and the invention consists in providing a locking memb r. such as a lag, formed on the under- I out slanting the chair.

length of the hole in the sleeper. The book may therefore be inserted in the hole withhen the hook has passed below the underface of the top, the ishort edge of the lug will engage the top face and b displacing the chair towards the side of the chair designed to lit into and complctelr till a hole formed in the top of the sleeper.

My nnprorcd chair dilfers from those of well known construction in that. the lug has 1 a hook which PIOJtCtS in the longitudinal d1- i rcction of the chair. The distance between the top face of the hook and the bottom of the chair is about twice as great as the; thickness of the top of the sleeper and the top face of the hook may be elther flat or curved.

In order that the invention may be clearly understood, reference is made to the accompanying drawings in which several cmbodiments are shown by way of example and in which Figures 1 and 2 are lon itudinal sections through the sleeper showing in elevation one outside of the track, as shown in Fig. l and towards the inside as shown in Fig. 3, the lug will fall into the hole and the hook be. passed beyond the edge of the hole and prevent the chair from being lifted oil the sleeper. This book and lug enter the hole in the sleeper at the outer side of the rail. as shown in Figs. .2, 4 and (3. It is therefore possible on the one hand to push the chair horizontally in between the tlange of the rail and the top of the sleeper without the chair being unintentionallv lifted oil when adjusting the track. 011 the other hand the gage. is etl'ectii'ci prevented from being reduced owing to the fact that the lug fills up the. hole and alteration thereof is not re quired.

The form illustrated in Figs. 5 and 6 differs from those described, in that the hook is form of the invention with the hook directed i outward from the rail. Figs. 3 and 4 are like views showing the hook directed in-I wardlv and Fi s. 5 and 6 are snnilar views 1 rail-chair by means of a hook p formed on 1" showing another modification.

S designates an iron sleeper provided with a hole a in its to 1.

A rail-chair 1) has a lug a on its under face,

' inner flange is engaged by a plate u.

a portion of said lug being of the same:

. edge of the tlange, the other edge being bevlcngth and breadth as the hole s so as to completely till the hole, and when the chair isin plat-con the sleeper, accidental dis-3 j through the plate and throu h a hole 8' U1 placement of the former is impossible.

One end of the lug is of substantially the not formed at right; angles with one end of the lug, but is curved. \Yith this form, the locking of the chair may be commenced when itis held slightly inclined and finished with a single push in the direction of the hook.

The rail indicated by t is secured to the the top face of the rail-chair adapted to take over the outer flange of the rail, while the This plate has one edge recessed to conform to the eled and resting on an incline p formed on the inner end of the chair. A bolt e passes the. sleeper and has a hook o'- formed on its lower end which takes under the top of the sleeper when turned into the position shown in Figs. 2, 4 and ti. A nut '0 on the upper tit) l l l t i g end of the bolt serves to depress the plate against the incline p which tends to force the rail flange against the hook 1).

As shown in Figs. 5 and 6, the hole in the sleeper is rounded at the underside which faces the curved portion of the hook. The additional advantage is that the edge 7: of said portion lies closer to the underface of the rail chair than in the construction shown in Figs. 1 to 4.

I claim 1. The combination with a metallic railway sleeper having a hole in its top on each side of the rail flange, of a rail chair extending over both holes having a lug on its underside near one end and of the same length as one of said holes to prevent longitudinal displacement of the chair, and a projecting portion of said lug with a horizontal prolonga tion distanced from the under face of the chair approximately twice the thickness of the sleepers to in said hole, and a clamping member engaging the other end of thechair and the rail flange and passing through the other hole.

2. The combination with a metallic railway slee r, having a hole in its top on each side of t e rail flange, of a rail chair extending over both holes provided with 9. lug on its underside near one end and having a portion the same length as one of said holes and filling said hole when in place to prevent longitudinal displacement of the chair, and a projecting portion of said lug with a horizontal prolongation slightly shorter than the hole and extendin lengthwise of the chair, distanced from t e under face of the chair a proximately twice the thickness of t 1e sleepers to a bolt passing through the other end 0 the chair and the other hole in the sleeper, and a clamping member engagitpg the edge of the rail flange held by said 3. The combination with an iron railway sleeper having a hole in its top, of a rail chair provided with a lug on its under side the same length as said hole and having a projecting portion slightly shorter than the role with a horizontal projection forming a hook whose upper face is at a distance from the sleeper approximately equal to the thickness of the sleepers top, whereby the lug may be inserted in the hole.

4. The combination with an iron railway sleeper having a hole in its top, of a rail chair provided with a lug on its under side of the same dimensions as said hole and a hook portion forming an extension of said lug and aving a lateral curved face, said hook poition distanced from the underside of the plhiiir to permit insertion of the lug in the In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
